Difficulty: EasyMobile Device Ports and Accessories

Match each mobile device port or wireless accessory technology on the left to its corresponding physical characteristic or primary capability on the right.

  • USB Type-CReversible 24-pin physical connector capable of carrying power, USB data, and video signals.
  • LightningProprietary 8-pin reversible connector used primarily on legacy Apple iOS devices.
  • Micro-USBNon-reversible 5-pin trapezoidal connector used on legacy Android and portable devices.
  • Near Field Communication (NFC)Short-range wireless technology (up to 4 cm) used for tap-to-pay services and quick accessory pairing.

Answer

USB Type-C matches the reversible 24-pin multi-function description; Lightning matches the proprietary Apple 8-pin reversible description; Micro-USB matches the non-reversible 5-pin trapezoidal description; and Near Field Communication (NFC) matches the short-range wireless technology description.
Each port and accessory technology matches its specific hardware definition: USB Type-C is a 24-pin reversible standard; Lightning is Apple's 8-pin reversible port; Micro-USB is a 5-pin non-reversible connector; NFC is a short-range contactless communication protocol.

Step-by-Step Solution

1
Identify the physical design attributes and pin configurations of each wired interface.
USB Type-C uses 24 reversible pins; Lightning uses 8 reversible pins; Micro-USB uses 5 directional pins.
Pin counts and insertion orientation distinguish physical mobile connectors from one another.
2
Identify the transmission range and purpose of the wireless technology.
NFC operates wirelessly within a 4 cm proximity envelope primarily for payment systems.
Separates wireless accessory capabilities from wired port standards.
